Summary: Solaris 2.3 to 2.5.1 upgrade

Thanks to all who responded, especially Dave Bevans and Glenn Satchell.

The solution was to use ufsdump/ufsrestore to create the new system disk
before upgrade.

Dave Bevans' response:

 -- Another possible issue is that when you rebuild a new drive from
     backups you should use the "ufsdump" utility as opposed to using
     "tar". The tar utility might not copy everything over completely.
     It's known that when rebuilding systems you can copy files over that
     may become corrupted or that the proper links were not established
     correctly. The ufsdump command will copy bit for bit and take a
     mirror image of the file system(s).

Glenn Satchell's response:

 -- Basically tar has problems with with path names greater
     than 100 characters which might affect you if you have deep
     directory structures.
